摘要： The invented process produces sorbic acid. The process includes the steps of adding a crude sorbic acid to a hot water having a temperature exceeding 100° C., which crude sorbic acid is obtained by the decomposition of a polyester formed through a reaction of ketene with crotonaldehyde, and performing at least one treatment selected from (A) a hot water extraction treatment for extracting sorbic acid with the hot water, and (B) a treatment with an activated carbon in the hot water. The temperature of the hot water is, for example, 120° C. or lower. The amount of sorbic acid to be treated is, for example, equal to or less than the saturated dissolution amount of sorbic acid with respect to the hot water at a treating temperature. The invented process can easily and efficiently remove tar substances and other impurities by-produced in the decomposition of the polyester and can produce a highly purified sorbic acid with a high productivity.

摘要： A plurality of speed-sliding compensation amount functions are stored in a sliding compensation amount data memory and one of these functions is selected in response to input of a selection signal. In the selected function, sliding compensation amount data corresponding to the speed of the object of positioning is read out. At least one of current position data and positioning target position data of the object is corrected by the read out sliding compensation amount data. A brake signal is generated on the basis of comparison of the current position data and target position data which have been subjected to this correction and a positioning control of the object is performed by this brake signal. On the other hand, a sliding amount detection circuit is provided for detecting sliding amount of the object from generation of the brake signal until actual stop of the object. The speed detected by a speed detector during generation of the brake signal is stored and, in accordance with the stored speed data and the detected sliding amount data, the selection signal for selecting the speed-sliding compensation amount function in the sliding compensation amount data memory is generated.

摘要： A detection head unit comprises a stator and a rotor. The stator has four poles disposed circumferentially at an interval of 90.degree.. The poles have primary coils and secondary coils wound thereon. Two radially opposing poles constitute a pole pair. The primary coils wound on the poles constituting the pole pair are connected in series and in opposite phase with each other and one pole pair is excited by a sine wave signal and the other pole pair by a cosine wave signal. The rotor is of such a configuration, e.g. an eccentric rotor, as to change reluctance of the respective stator poles in accordance with a rotation angle and change reluctance in a differential manner between the two poles constituting the pole pair. An output signal resulting by phase shifting the sine wave signal applied to the primary coil in accordance with a rotation angle of the rotor is provided by a secondary coil. The rotation angle is detected by measuring phase difference between the reference signal and the output signal of the secondary coil. The rotation speed can be detected by detecting difference in frequency or period between the reference signal and the output signal. Further, acceleration in rotation can be detected by detecting an amount of change in the rotation speed. The detection device of a high resolution can be obtained by providing teeth of a certain pitch on the periphery of the rotor and teeth corresponding to the rotor teeth on the stator poles.

摘要： About a bobbin, there are wound primary coils in axially displaced locations and wound also is a secondary coil. A core is linearly slidably provided in the bobbin. The primary coils are individually excited by AC signals which are out of phase with each other, e.g. a sine wave signal and a cosine wave signal. The secondary coil thereupon produces an output signal resulting from phase shifting the applied sine or cosine wave signal in accordance with a linear position of the core. Accordingly, the linear position can be detected by measuring phase difference between a reference AC signal and the output signal of the secondary coil. Likewise, velocity and acceleration change may be determined using the position change data.
